摘 要: In this talk, we will give the upper bound of the number of points of any $\pi/2$-separate subset in an $n$-dimensional Alexandrov space $M$ with curvature $\geq 1$. And we will classify the (topology or geometry) structure of $M$ when the number attains the upper bound. This is based on a joint work with Xiaole Su and Hongwei Sun.
